That was just an example. The actual binding in LP-8x4x is bigger:
fpga@5 {
compatible = "simple-bus";
#address-cells = <1>;
#size-cells = <1>;
ranges = <0 5 0x3000000 0x10000>;
interrupt-parent = <&fpgairq>;
rtc@901c {
compatible = "dallas,rtc-ds1302";
reg = <0x901c 0x1>;
status = "okay";
};
sram@a000 {
compatible = "icpdas,sram-lp8x4x";
reg = <0xa000 0x1000
0x901e 0x1>;
partitions {
#address-cells = <1>;
#size-cells = <1>;
};
};
fpgairq: irq@9006 {
compatible = "icpdas,irq-lp8x4x";
reg = <0x9006 0x16>;
interrupt-parent = <&gpio>;
interrupts = <3 IRQ_TYPE_EDGE_FALLING>;
#interrupt-cells = <1>;
interrupt-controller;
status = "okay";
};
uart@9050 {
compatible = "icpdas,uart-lp8x4x";
reg = <0x9050 0x10
0x9030 0x02>;
interrupts = <13>;
status = "okay";
};
uart@9060 {
compatible = "icpdas,uart-lp8x4x";
reg = <0x9060 0x10
0x9032 0x02>;
interrupts = <14>;
status = "okay";
};
uart@9070 {
compatible = "icpdas,uart-lp8x4x";
reg = <0x9070 0x10
0x9034 0x02>;
interrupts = <15>;
status = "okay";
};
backplane {

reg = <0x0 0x2
